Sometime today all the articles on my blog reverted to Uncategorized, all the Tags went away, and the Blog Roll became empty. Whether this is related to a post-failure restore by my hosting service last night or not, I can't be sure (my guess is not). The problem affects 4 different blogs.
In the Admin interface, Categories says "96" entries, but the list has "no items found."
If I list Links in the admin interface, the links are there with the correct Link Category names, but if I list the Link categories, it says "6 entries" but the list has "no items found."
When I look at Tags in the Admin interface, they are all there with counts; however, if I click to view any of them, noting is displayed.
I've poked in the WordPress database tables and they look right so far as I can tell. I can see the actual items in WP_TERMS and the ID's match up to the WP_LINKS table
This makes me speculate that queries are broken and that my hosting company may have changed something.
I'm in a mess.
